A man who was injured in an assault in Golden Gate Park after the Bay to Breakers race has died, according to the San Francisco Medical Examiner's Office.

Santa Clara resident Stephen Martin, 30, died Friday after he was taken off life support, according to a statement posted by his family to a Facebook page. He had suffered what doctors called "unrecoverable brain damage, according to the statement.

Martin was assaulted May 20 shortly before 5 p.m. in the Sharon Meadows area of the park near the Sharon Art Studio and tennis courts, police said.

He was with friends who had attended the Bay to Breakers race earlier that day. He and his friends were dressed as troll dolls, according to police.

They were standing near a second group of about a dozen people and an argument broke out between the two groups, police said.

Police said some of the women in the second group were wearing purple and one was wearing an orange tutu, while the males were wearing red and white 49ers jerseys.

A man from the second group punched Martin, who fell and struck his head on the ground and lost consciousness.

Following the assault, police issued a call for witnesses or for anyone with photos and video from the area where the fight occurred to come forward. A police spokesman today said no new information was available on the investigation.
